Best fan curve for my PC?

[MrManWho]

I was just wondering what the best fan curve would be for my PC, I don't know what specs I should post, just let me know if anyone is willing to help.

Your motherboard, CPU, GPU, and Case. Also will need to know what type of fans you have, 3 pin, 4 pin, make/model and what you're looking to accomplish with said curve.

Generally I would say that the best fan curve for all PC's, are the fan curve that gives you the most airflow, without sounding like a jet engine. 

That said though, this is how I tune my fan curves: 

At idle, I aim for the lowest possible fan RPM, while still holding proper idle temps. I do this because when my PC isn't doing anything special, fx gaming, and doesn't need huge amount of airflow / cooling, I want to minimize the dust intake. 

Then at load, I tune the fan curve to the highest RPM, while still being quiet. This is also because I'm using speakers while gaming. 

Sure, if you're using a headset, you could just crank the fan curve to 100%, because you can't hear the fans anyway, but I still wouldn't recommend this. Tune the fan curve to the lowest RPM possible, while still holding acceptable temps, so you minimize dust intake.

And also the kind of cooling on your CPU (and GPU if it is aftermarket one) - air, AIO or custom loop, what model(s) or how many rads etc.

For me, it’s mainly about maintaining a desired noise level (without sudden jumps in noise) whilst maintaining healthy temps in both idle & heavy use cases.

 

I keep a flat line PWM that spans just beyond typical idle temps (including sudden jumps in temp when Windows does its own random (temporary) background tasks.

 

For my case/fan enclosure, CPU & GPU sit around ~33-36° idle, with the CPU jumping to 50° when Windows does random background tasks, so I have my flat line PWM set up to 60° to cover that range of temp movement.

 

My most intense tasks are games, so the CPU doesn’t jump too high in temp compared to the GPU. Here are my curves for my two sets of fans. 

 

CPU focussed case (& tower) fans…Steeper fan curve to jump on CPU temps rising above 60°…

 

GPU focused case fans…More gradual fan curve as the GPU has its own fans that are very good at keeping temps down…

 

NOTE: My RPMs are what works for my particular case fan performance within my specific case. Yours will differ. This is why there's no one best solution - everyone's setup is different, so it's about trialling different PWMs & maybe fan types/quantity & placement within your case that gets you toward your ideal noise/performance goals.

 

The more familiar you are with your system, the better.

 

Good luck, bud.
